issue: https://github.com/google/adk-python/issues/982
This pull request introduces a new configuration option, `realtime_input_config`, to the `RunConfig` class.
**Reason for this change:**
Currently, there is no direct way to configure real-time audio input behaviors, such as Voice Activity Detection (VAD), for live agents through the `RunConfig`. The Gemini API documentation (specifically [Configure automatic VAD](https://ai.google.dev/gemini-api/docs/live#configure-automatic-vad)) outlines parameters for VAD that users may want to customize.
This change enables users to pass these real-time input configurations, providing more granular control over the audio input for live agents.
**Changes made:**
- Added a new optional field `realtime_input_config: Optional[types.RealtimeInputConfig]` to the `RunConfig` class.
- The docstring for `realtime_input_config` has been added to explain its purpose.
**Example Usage (Conceptual):**
While the specific structure of `types.RealtimeInputConfig` would define the exact parameters, a user might configure it like this:
```python
# (Assuming types.RealtimeInputConfig and types.VadConfig are defined elsewhere)
# import your_project.types as types
run_config = RunConfig(
# ... other configurations ...
realtime_input_config=types.RealtimeInputConfig(
automatic_activity_detection =types.AutomaticActivityDetection(
# VAD specific parameters like sensitivity, endpoint_duration_millis etc.
# based on https://ai.google.dev/gemini-api/docs/live#configure-automatic-vad
)
# Potentially other real-time input settings could be added here in the future
)
)

This allows to protect against any write operations (e.g. update or delete a table), useful for some agents that must only be used in a read-only mode, while the user may have write permissions.

### Description
When using the Google.GenAI backend (GEMINI_API), file uploads fail if the `file_data` or `inline_data` parts of the request contain a `display_name`. The Gemini API (non-Vertex) does not support this attribute, causing a `ValueError`.
This commit updates the `_preprocess_request` method in the `Gemini` class to sanitize the request. It now iterates through all content parts and sets `display_name` to `None` if the determined backend is `GEMINI_API`. This ensures compatibility, similar to the existing handling of the `labels` attribute.
Fixes#1182
### Testing Plan
**1. Unit Tests**
- Added a new parameterized test `test_preprocess_request_handles_backend_specific_fields` to `tests/unittests/models/test_google_llm.py`.
- This test verifies:
- When the backend is `GEMINI_API`, `display_name` in `file_data` and `inline_data` is correctly set to `None`.
- When the backend is `VERTEX_AI`, `display_name` remains unchanged.
- All unit tests passed successfully.

**2. Manual End-to-End (E2E) Test**
I manually verified the fix using `adk web`. The test was configured to use a **Google AI Studio API key**, which is the scenario where the bug occurs.
- **Before the fix:**
When uploading a file, the request failed with the error: `{"error": "display_name parameter is not supported in Gemini API."}`. This confirms the bug.

- **After the fix:**
With the patch applied, the same file upload was processed successfully. The agent correctly analyzed the file and responded without errors.

The `Args:` section in the docstring of the `cli_deploy_agent_engine` function was causing formatting issues in the help output, with line breaks not being rendered correctly.
This commit removes the redundant `Args:` section from the docstring. The help text for options is already comprehensively covered by the `help` attributes in the `@click.option` decorators, and `click` automatically lists the command's arguments.
This change ensures that the help output for
`adk deploy agent_engine --help` is clean, readable, and correctly formatted, relying on `click`'s standard help generation mechanisms.
After the fix:
